Install Splunk Enterprise securely

To install Splunk Enterprise securely, you must have an installation package that you have confirmed is authentic and has not been modified in any way since Splunk created it. Splunk provides a Message Digest 5 (MD5) secure hash for every package it generates. You can download this hash to quickly verify that the package you downloaded is authentic and has not been changed since its creation.

You can also compare the Secure Hash Algorithm-512 (SHA-512) hashes by opening a case with Splunk Support.

Prerequisites for verifying package integrity

You must have the following to verify the contents of packages you download:

The md5sum program, which prints the hash of the file that you supply, and comes with most versions of Linux. On Windows, you can use the certutil tool to verify MD5 hashes.

Alternatively, the sha512sum program prints SHA512 hashes for the file that you supply.

The MD5 or SHA512 hashes, in text format, which Splunk provide

Access to a shell prompt

Verify installation package integrity

After you download the Splunk Enterprise package, verify it by using a trusted version of the OpenSSL suite to compare the MD5 or SHA-512 hashes to the hash of the installation package. If the hash of the package you downloaded matches the hash that Splunk provides, then you have downloaded a valid, secure installation package and can proceed with installation.

Download Splunk Enterprise installation package and MD5 hash

Confirm that you download the MD5 hash that exactly matches the version of installation package that you downloaded. Downloading a different file results in the hashes not matching.
